Abstract

A sealing liquid device (60) includes an annular packing made of rubber-like elastic material, the annular packing having a secured section fitted with fluid tight to one retaining surface between a first stationary seal ring (3) and a seal flange and having a seal lip section fitting to the other contact face for sealing. Even high viscosity fluid or slurry-contained fluid can be securely sealed without deficiency of a liquid sealing device.
